Tornado Warning! ⚠️

07/04/2024

Probability of Watch Issuance...5 percent

SUMMARY...An isolated threat for strong/gusty winds and perhaps a
brief tornado may exist with any low-topped thunderstorms that can
develop. Watch issuance is not expected.

DISCUSSION...Recent visible satellite imagery shows a cu field
gradually deepening across IA and vicinity along an occluded front
extending eastward from a deep surface low in northeastern NE.
Low-topped convection has recently developed in far southeastern SD,
in close proximity to the surface low. Boundary-layer moisture
remains modest across this region, with surface dewpoints generally
in the mid 40s to around 50. Still, filtered diurnal heating of this
airmass is contributing to around 75-125 J/kg of 0-3 km MLCAPE in a
narrow zone focused along the front per latest mesoanalysis
estimates. Near-surface vorticity is also likely maximized along
this boundary, with modest low-level shear present based on recent
VWPs from KDMX/KDVN.

Even with the moisture/instability limitations, there should be some
chance for ongoing low-topped thunderstorms to gradually increase in
coverage and intensity over the next few hours this afternoon into
IA and perhaps northwestern IL. Given steepened lapse rates through
the cloud-bearing layer, isolated strong/gusty winds appear possible
with the more robust cores. A brief tornado/landspout or two may
also occur, mainly focused along the occluded front where
near-surface vorticity overlaps with maximized 0-3 km CAPE and steep
boundary-layer lapse rates. However, the overall severe threat this
afternoon is expected to remain too isolated/marginal to justify
watch issuance.

A rare and potentially significant weather event is set to take aim on the upper midwest, an event that could bring significant snow to the area Thursday thru Tuesday of THIS week. We were first aware of this system last week. The first image is GFS model and the last is ECMWF model.
At this time current trends suggest a powerful system to take place over the region, with current totals 7-10 inches in NE Iowa , 10-14 in SE Minnesota/ SW Wisconsin and 12+ possible near the Twin Cities.
For the last several days, we have watched these numbers stay mostly the same, and being less than a week out, that is cause for concern, especially for those traveling.
** This is not a forecast, also, the totals that are projected are from this Thursday thru next Tuesday.

Slow moving snow squall

27/02/2024

SNow squall alert. - SUMMARY...A heavy band of snow will continue east with occasional
snow squall conditions possible.

DISCUSSION...A band of snow along the 700mb front continues
southeast this afternoon with brief snowfall rates in excess of 1
inch per hour. In addition, this snow band is within a broad
synoptic environment featuring 20 to 30 knot northwesterly sustained
surface winds. Therefore, this combination is leading to reduced
visibility within the line from east-central Minnesota to eastern
Nebraska. Guidance indicates this band of snow should maintain
intensity as it moves east this evening
